SPECIFICATION arming' part of Letters Patent No. 589,237, dated August31,1897.

Application sied May 25, 1897.

Be it known that I, WlLLIAM B. BAKER, a citizen of the United States,residing at Newport News, in the county ofrWarwick and State ofVirginia, have invented new and useful Improvements in a Combined BeerTap, Cooler, and Pump, of which the following is a specification.

This invention relatesto a combined beer tap, cooler, and pump; and itconsists in the novel features of construction and combinations of partsin such an apparatus, as hereinafter described and claimed; In theannexed drawings, Figure 1 is a perspective view showing the arrangementof parts in a beer tap, cooler, and pump constructed according to myinvention. Fig. 2

is an enlarged' sectional view of the pumpwith bar-faucet in sideelevation. Fig. 3 is atop view of the pump and bar-faucet. Fig. 4 is aplan of the cooler with cover removed. Fig. 5 is a cross-sectionalelevation of the cooler. Fig. 6 is an enlarged sectional elevation ofthe drawing-olf pipe, bung-plug pro? vided with stuffing-box, and arecessed bungdriver surrounding the drawing-off pipe and normallyresting on the bung-plug. Fig. 7 is a plan or top view of the bung-plugwith drawing-off pipe in cross-section.

Referring to the drawings, the numeral 1 designates a barrel or keg fromwhich beer is to be forced into and through a cooling-coil or tortuouspassage 2, Figs. 4 and 5, located in the lower part of arefrigerating-tank or ice-chest 3, Fig. 1, supported at a convenientelevation for drawing off the beverage as required.

There is inserted into the bun g-hole or suitable aperture of the keg aconical metal plug 4, Figs. 1 and 6, having a somewhat enlargedcylindrical head 5, as shown. This bungplug4 and head 5 are centrallybored for passage of a drawing-off pipe G, having in its lower end aseries of inlet-openings 7, through which the liquid contained in thekeg will enter the said pipe under the pressure of the gas in the keg orby an air-pressure forced onto the surface of the liquid, as presentlyexplained.y

Between the pipe 6 and the bore of the plug 4 there is a sufficientannular passage saai no. 638,109. (No modem 4t, Fig. G, to permit theintroduction of air into the keg through an vairinlet nozzle S, tappedinto the head 5 of said plug. On the outer side of the head 5 there isan externally-threaded boss 9 for engagement of a hand-nut or screw-capl0, which is suitably recessed to inclose a washer or packing 11 formaking a stuffing-box or close joint around the vpipe 6 outside oftheplug` 4 to prevent the escape of gas or air from the keg.

Surrounding the pipe (i and normally resting on the plug-head 5 there isa cylindrical plug-driver 12, Figs. 1 and 6, which is suitably recessedor cored to inclose or surround the nut or boxing 10, so as to preventjanr ming or other injury thereto in driving the plug. The plug-driver12 is provided with a handle 13, also surrounding the pipe 6, and whichcan be convenientlygrasped for actuatin g the driver to force the pluginto place.

It Will be observed that the plug-driver completely surrounds thedrawing-off pipe G and rests normally on the head 5 of the bungplug 4,so that it is always ready for instant use. By providing this driverthere will be no need for employing an ordinary hammer or mallet todrive the plug, and which would be liable to deliver its blows unequallyand jam or mash the plug-head and nut. The plug-driver 12, beingoperated on the pipe G as a guide and never in contact with the nut 10,cannot possibly injure the said nut or stuffing-box and will alwaysdrive the plug true and without battering or mashing.

At a convenient point on the pipe 6 there is preferably provided a cock14, that may be closed whenit is desired to disconnect the drawing-offpipe from the keg. By means of a screw-coupling 15 there maybe attachedto the pipe 6 or cock 14, as shown, an elbow 16, from which is extendeda suitable length of flexible tubing 17 to connect with a short piece ofpipe or pipe-coupling 18, which in turn connects with the inlet-nozzle19 to the cooling-coil or lengthencd tortuous passage 2 in the ice-chestor refrigerating-tank.

The coil or tortuous passage 2 is inclosed in a casing 20, removablylocated in the lower part of an ice chest or chamber 3 of any suitableconstruction. This tortuous passage 2 may be formed in any convenientmanner in IOO the bottom part of the casing 20, and the said casing iscovered by a lid or plate 2l, fastened to the casing in such manner asto be removable. Ice is to be placed upon this plate or casiugcover 2land around the casing 20, so that the beer, in passing through thelengthened passage or coil 2, will be thoroughly cooled. At thetermination of the coiled or tortuous passage 2 there 'is an exit-nozzle22 for connection with a bar-faucet 23, through which the cooled beer isto be drawn.

The faucet 23 may be provided with a lug 24, to the sides of which arepivotally attached two links 25, that pivotally connect with thebifurcated end of a hand-lever 2G, having an arm 27, that is jointed toor pivotally connected with the piston-rod 2S of an air-pump that islocated in the upper part of the ice chamber or chest. It will beobserved that the linked connection of the hand-lever 26 with itssupport alfords a movable fulerum for said hand-lever, which with thejointed connection of the lever-arm 27 and piston-rod 28 will cause thepump-piston to move always in a straight line.

The air-pu1np cylinder 29 is connected to a plate 30 to be secured onthe outside of the refrigeratin g chamber, tank, or chest. A depending`extension 3l of this plate 30 will afford support for the faucet 23,through which the beeror otherliquid is drawn. 0n the air-pump cylinder29 there is an annular flange 32 at a distance from the plate 30 aboutequal to the thickness of the ice-chest wall. The plate 30 is on theouter side of this wall and the flange 32 is on the inner side. Bolts33, extended through the plate 30, ice-chest wall, and flange 32, willserve to rigidly secure the air-pump in position.

The piston-head of the air-pu 1n p consists of two plates 34 and 35,between which an expansible packing 3G is secured. One of the plates, as34, may be rigid on the piston-rod 28 or held against a shoulderthereon. The other head 35 'is slipped onto the piston-rod after thepacking 3G has been put in place. This head or plate 35 is cupped, asshown, or peripherally flanged to afford support for the extended rim ofthe packing 36, vwhich is bet-ween the bore of the cylinder 29 and theflanged rim of said plate 35, and in order to subject the packing tocompression and force it firmly and expansively against thecylinder-bore there is provided a spring 37, held by a cap 38 and nut3S) on the end of the piston-rod. Obviously the nut 39 can be tightenedso as to cause the spring 37 and plate 35 to exert any requiredcompression and peripheral expansion of the packing.

The inner end of the air-pump cylinder is screw-threaded forconnectionof a removable head 40 with a packing-ring 4l interposed. Thiscylinder-head 40 is perforated for attachment of a pipe 42,whichconnects,through a T-coupling 43, with branch pipes 44 an d 45, one forinlet of air to the pump-cylinder and the other for exit of air undercompression to be forced into the beer keg or barrel l when necessary.lu each of the branch pipes 44 and 45 there is located a cheek-valve 46of suitable construction. The air-exit pipe, as 45, will be extended outside the ice-chest or refrigerating-chamber through one wall thereof,and to this pipe is attached a suitable length of flexible tubing 47 toconnect with the air-inlet nozzle 8 on the bung-plug 4 at the beer-keg.Thus whenever the pressure oi' gas in the keg or liquid-receptacle isinsufiicient to force the beer orother liquid through the pipe (3,tubing 17, and cooling coil or passage 2 the air pump can be operated bymeans of the handflever 26 to force-the beer to the coil or passage 2,whence it may be drawn by the bar-faucet.

As the air-pump is located within the icechcst and takes its supply ofair therefrom the liquid in the keg, barrel, or other receptacle will besubjected to direct action of this cold air when the pump is operated.On reaching the lengthened passage or coil in the icechest the liquidwill be still further cooled therein before it is finally drawn off foruse.
